Cherrypick ac38465: Handle bionic in safe_strerror_posix as well as glibc.

> Android's bionic C library is intending to adopt the same semantics as
> glibc for strerror_r: define the version that returns char* if the
> source is compiled with _GNU_SOURCE instead of the POSIX version which
> returns int. Add __BIONIC__ to the condition for
> USE_HISTORICAL_STRERRO_R so that Chromium will still work.
